I’ve found Culture Queries to be a good resource for this. Helped me avoid questions that led to boilerplate answers (“do you have work/life balance?” -> “How responsive are people to emails/Slack over the weekends and after 6pm?”).
Yes. Just asking about work life balance always tends to get boilerplate answers ("Of course we do!"). This is a great way to get that same info without making them produce those selling point ones.
That and asking a specific question let's you find out what they actually consider W/L balance to be - i.e. I assume a group of 25 year olds probably see their jobs differently to people twice that age with kids (I'm reminded of Lex Fridman asking Jim Keller what his greatest achievement was, and him basically saying I have kids or something to that effect)
